Benefits of technology

"The present invention provides a child restraint system that improves crash behavior of the child restraint and reduces misuse. The system includes a base that is attached to the vehicle seat and a child seat that is releasably connected to the base. The base has an impact absorbing mechanism in the form of at least one ISOFIX connector and at least one blocker element that can slide into the voids in the base. The blocker element is force-loaded and can lock the ISOFIX connectors in place during a collision. The system also includes a holding device to hold the ISOFIX connectors in their innermost position in the voids. The child restraint system reduces the rotation of the child seat during a crash and minimizes the risk of misuse."

Problems solved by technology

Since the impact energy from the collision has partly been absorbed in the process of bringing the blocker element out of abutment with the ISOFIX connector, the remaining impact energy will not be able to rotate the child restraint as much, as if not the energy has been absorbed.

Embodiment Construction

[0031]FIG. 1 shows a child restraint system 1 according to the present invention, where the child restraint is intended to be used both in a forward-facing position (shown on the left side in FIG. 1) and a rearward-facing position (shown on the right side in FIG. 1). The child restraint system 1 comprises a base 2 and a child seat 3 that is releasable connected to the base 2. The base 2 is provided with two ISOFIX connectors 4, such that the base 2 can be connected to standard anchorage points 12 (see FIG. 3) arranged in a vehicle seat 13. The ISOFIX connector 4 is in the form of a bar and is slidably arranged within a void 8 in the base 3. A seat support 5 is connected to the base 3, where the seat support 5 through a tightening and releasing mechanism can be brought in or out of abutment with a back portion of the vehicle seat 13. This will fit the child restraint securely in the vehicle seat when the child restraint is used with the ISOFIX connectors 4. In order to further secure...

Abstract

The present invention relates to a child restraint system (1) with a base (2) having a lower surface resting on a sitting portion of a vehicle, where the base (2) through ISOFIX latching means is engaged with anchorage means (12) in the vehicle seat (13), thereby providing a pivot connection between the base (2) and the anchorage means (12). Through an energy absorbing mechanism (7) impact energy can be absorbed, thus reducing the degree of rotation of the child restraint (1).

Description

FIELD OF THE INVENTION[0001]The present invention relates to a child restraint system for use in a vehicle with seat assembly equipped with standard anchorage units. The child restraint system may also be used in a vehicle using a safety belt or other securing means. More particularly the present invention relates to an energy absorbing child restraint system.BACKGROUND[0002]Most child restraint systems are currently designed to be fitted in a vehicle seat and secured to it by using a vehicle's adult lap and diagonal seat belt, or sometimes just the lap belt. However, vehicle seats, seat belts and their anchorages vary greatly between different models of vehicles; the seats have different shapes, the seat belts may be shorter or longer, the position of the anchor points differs etc. All these factors make it virtually impossible to make a child restraint system that fits in all vehicles and this sometimes make it complicated or even impossible to fit the child restraint system corre...
